Effect of expanded process on in vitro digestibility of feedstuff in Ctenopharyngodon idellus

Guo Jianlin Ye Yuantu et al.  
This experiment was conducted to study effects of expanded process on in vitro digestisility of feedstuff in Ctenopharyngodon idellus.The feedstuffs in the trial were rapeseed,rape-wheat(rapeseed:wheat,1∶1),soy-wheat(soybean:wheat,1∶1).The results showed that the in vitro dry matter digestibility of feedstuff in Ctenopharyngodon idellas were:expanded rapeseed(23.46 %)unexpanded rapeseed(22.21 %),expanded rape-wheat(26.95 %) unexpanded rape-wheat(15.74 %),expanded soy-wheat(32.79 %)unexpanded soy-wheat(19.36 %);the in vitro digesibility of crude protein were:rapeseed(46.36 %)expanded rapeseed(38.51 %),expanded rape-wheat(39.24 %)unexpanded rape-wheat(28.34 %),expanded soy-wheat(52.43 %)unexpanded soy-wheat(46.16 %);the in vitro digestibility of crude fat were:expanded rapeseed(44.71 %)unexpanded rapeseed(44.24 %),expanded rape-wheat(36.59 %)unexpanded rape-wheat(29.00 %),expanded soy-wheat(43.54 %)unexpanded soy-wheat(30.04 %).The results suggested that Ctenopharyngodon idellus had a high digestibility to expanded feedstuff,especially the feedstuff with high content of starch.
